To all whom it Hetty concern.'

Be it known that I, HORACE M. YORKE, a citizen of the United States,residing at Kennebunk, in the county of York and State of Maine, haveinvented a new Sectional Checker-Board; and I hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled inlthe art to which it appertains tomake and use the same.

My invention relates to a sectional checkerboard.

In the drawings, Figure 1 is a to plan. Fig. 2 is a top plan showingpart of t e sections in place and illustrating the method of placingthe' sections. Fig. 3 is a detail showing in perspective a portion ofthe frame. Fig. 4 is a perspective view of a corner of the frame,showing the clasp for connecting the corners. Fig. 5 is a detail showingin perspective a portion of the sections of the board with black andwhite squares thereon, and Fig. 6 is a view in perspective of a cornerof the frame, showing the aperture for receiving the pin on the clas Itis the purpose ofP my invention to provide a sectional checker-board soconstructed that it may be taken apart and packed in the smallestpossible compass.

The board proper consists of eight sections B B, the face of eachsection being equal in width to the width of a square on the board andthe length of such face equal to eight of such squares. These sectionswhen con structed of wood or similar material should be provided uponone edge, as shown in Fig. 5, with a tongue t and upon the other edgewith a groove g. The face of these sections are the same, except thatfour of them will commence with a black square on the lefthand side andfour commence with white square on the same side, the groove in eachinstance being uppermost. For the purpose of connecting together inproper relation the sections already described I make use of a frame AA, consisting of four parts, as sh own in Figs. l and 2. Each of thefour pieces is identical, save that at each end two of the pieces areprovided with a clasp C, which is securely attached to the frame, asshown in Figs. l and 2 and also in Fig. 4. This clasp C is constructed,preferably, of metal having a slight spring, and the free end isprovided on the inner side with a pin D. (See Figs. 2 and 4.) At eachend of the other two pieces of the frame A A an aperture e, adapted toreceive the pin D, is provided, as shown in Figs. 2 and 6. The frame A Ais provided with a groove 7L throughout the inner edge of uniformthickness and depth and of such width as to admit the ends of thesections B B and also the upper and lower sides of the upper and lowersections B B, which are made somewhat wider on the upper and lowersides, respectively, than the other .sections.

In operation the two side pieces and the bottoni piece of the frame areconnected by means of the clasp and pin, as shown in Fig. 2. The bottomsection B is now inserted between the sides so formed and carrieddownward until its lower edge is rmly set in the lower part of theframe. The sections are now inserted so that the black and white squareswill alternate, as shown in Fig. 2, until seven sections have beeninserted, when the eighth section, having a space upon the upper edge,is inserted and the upper piece of the frame put into position and thepins of the clasp in the apertures e near the top of the side piecesAA.The board is now in condition for use. When it is desired to take theboard apart and place it in some receptacle for travel or for any otherpurpose, the operaltion is reversed. The upper part of the frame isfirst released from the side pieces and the sections removed and thenpacked closely together in a boX or such other receptacle as may beused.

It may be found, and indeed I believe it to i,

be, advisable to make an additional space at the end of each section andat the top and bottom edge of the top and bottom sections and of suchwidth that the squares of the board when put together will not be incon- 9 tact with the. frame A, but present a space between the outermostsquares and the frame The space between the frame and squares may bevaried as desired.

In the foregoing description I have consid ered the board as made ofwood or similar material. If, however, as may be desirable, it isconstructed of thin plates of steel or other metal, the tongues t t andgrooves g g in the edges of the sections can be omitted, as thestiffness of the metal and its freedom from warping will permit thesections to lie and remain close together.

For the purpose of connecting the corners of the frame I do not,however, confine my- TOO self, whatever may be the material used, to theuse of the clasp shown in the drawings. Other convenient means may beused, such as a yoke adapted to swing over a pin or a swinging plateadapted to connect with a pin. Other means will readily suggestthemselves.

What I claim is- 1. A sectional checker-board consisting of sectionsalternately provided with the requisite squares and a suitable framewhereby the sides of the top and bottom sections and the ends of all thesections may be held in place and means whereby said frame may belocked, substantially as described.

2. A sectional checker-board combining eight sections provided withalternate white and black squares and means whereby said sections may,when arranged as a checker- HORACE M. YORKE.
